Product details

Overview

ES3F M6G from Taiwan Semiconductor is a 3A, 300V super fast recovery surface-mount rectifier in DO-214AB (SMC) package, featuring 35ns reverse recovery time, 1.30V max forward voltage at 3A/25°C, and 100A peak surge current - used in high-frequency switching mode power supplies for telecom and computing.

For engineers reviewing the ES3F M6G datasheet, ES3F M6G pinout, ES3F M6G application, or ES3F M6G equivalent, key selection criteria include V_RRM = 300V, I_F = 3A, t_rr = 35ns, R_θJA = 47°C/W, and DO-214AB mechanical compatibility with automated SMT assembly.

Technical Context

This single-die, glass-passivated super fast rectifier operates with junction temperatures from –55°C to +150°C and supports high-efficiency DC/DC conversion where low forward voltage drop and rapid reverse recovery minimize switching losses. Its 30pF junction capacitance at 1MHz/4V enables stable performance in MHz-range SMPS topologies.

The device meets J-STD-020 moisture sensitivity level 1 and JESD201 Class 2 whisker resistance, with matte tin-plated leads solderable per J-STD-002 - confirming suitability for lead-free reflow and high-reliability industrial production environments.

Equivalent & Alternatives

The following parts are listed as comparable options for similar super fast rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-ES3FHM3	V_RRM = 300V, t_rr = 35ns, V_F = 1.30V, same DO-214AB package but with green molding compound	Identical electrical specs; differs only in material composition (halogen-free status not explicitly stated in public datasheet)	Select when requiring Vishay's qualification documentation or specific supply chain diversification
ON Semiconductor MUR330	V_RRM = 300V, t_rr = 35ns, but V_F = 1.35V (max), R_θJA = 50°C/W, same DO-214AB footprint	Slightly higher conduction loss and thermal resistance; validated for automotive-grade temperature cycling	Prefer when AEC-Q101 qualification is mandatory, despite marginal efficiency trade-off

Compared with VS-ES3FHM3 and MUR330, ES3F M6G delivers identical t_rr and V_F performance in a halogen-free, J-STD-020 Level-1 compliant package - making it optimal for cost-sensitive, high-volume telecom and industrial power supplies where moisture handling and environmental compliance are prioritized.

FAQ

What is the maximum junction temperature rating for ES3F M6G?

The ES3F M6G has a maximum junction temperature (T_JMAX) of +150°C, with operational range from –55°C to +150°C. This rating allows reliable use in enclosed, fanless power supplies where ambient temperatures may reach 70–85°C, provided thermal design maintains junction temperature below 150°C under worst-case load and airflow conditions. The ES3F M6G's R_θJA = 47°C/W must be applied with appropriate copper area and airflow assumptions.

Does ES3F M6G meet RoHS and halogen-free requirements?

Yes, ES3F M6G is RoHS compliant and halogen-free per IEC 61249-2-21. The device uses molding compound and plating materials that contain no brominated flame retardants, chlorine, or fluorine above threshold limits. This compliance is verified in Taiwan Semiconductor's official product declaration and applies to all units shipped under ordering code ES3F M6G - critical for CE marking and export to EU, Japan, and South Korea markets.

What is the reverse recovery time (t_rr) test condition for ES3F M6G?

The reverse recovery time of 35 ns for ES3F M6G is measured under standardized conditions: I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A, with specified di/dt and voltage ramp rates per JEDEC standards. This value is guaranteed maximum - typical performance is tighter. The ES3F M6G's t_rr remains stable across its full operating temperature range, supporting consistent efficiency in variable-temperature environments.

Is ES3F M6G suitable for lead-free reflow soldering?

Yes, ES3F M6G features matte tin-plated leads qualified per J-STD-002 for solderability and is rated for lead-free reflow profiles up to 260°C peak temperature. Its moisture sensitivity level is J-STD-020 Level 1, meaning it can be stored indefinitely at ≤30°C/60% RH without baking prior to assembly - eliminating process steps and reducing risk of popcorning during reflow. This makes ES3F M6G fully compatible with modern high-speed SMT lines.

How does the forward voltage of ES3F M6G compare to ES3A–ES3D variants?

ES3F M6G has a maximum forward voltage of 1.30 V at I_F = 3 A and T_J = 25°C, whereas ES3A–ES3D variants specify 0.95 V max under identical conditions. This difference reflects the higher V_RRM (300 V vs. 50–200 V) and optimized doping profile for higher-voltage blocking - resulting in slightly higher conduction loss but enabling safe operation in 300 V-rated circuits where ES3A–ES3D would fail catastrophically. The ES3F M6G remains optimal for 300 V applications.
